Although scholarship has long recognized the centrality of the Trinity in the theology of Hans Urs von Balthasar, no sustained treatment of this theme has been undertaken. In this insightful new study, Brendan McInerny fills this gap, situating Balthasar’s Trinitarian theology in conversation both with the wider Christian theological tradition and with his non-Christian intellectual contemporaries. Drawing from across Balthasar’s extensive body of works, McInerny argues that Balthasar’s vivid description of the immanent Trinity provides a way to speak of how “God is love” in himself, beyond his relationship to creatures. He then shows how Balthasar’s speculation into the immanent Trinity serves as the substructure of his theology of deification.
